Let's assume that the distance between two tables is 7 inches and the weight is hanging in the middle. The equation is as follows: M = PL / 4W = b * h * H / 6 σ = m / w = 3PL / (2B * h * h) H = 297 / Nb = n * th / b ≤ 4. In the formula above, t is the thickness of paper plus glue, and the thickness of paper is about 0.07mm
